Staging plan. For any area to be developed in stages, the developer shall submit a total development plan in such detail as required by the approving authority with a staging plan showing the following:

The anticipated date for commencing construction of each state. The staging shall be such that if development of the site were discontinued after the completion of any stage, the developed portion would comply with all requirements of this chapter and be provided with adequate drainage and utility systems.

The improvements to be completed in each stage prior to application for certificates of occupancy shall be shown. The plan should demonstrate that subsequent stages will have minimum adverse effects upon occupied buildings on the site and adjoining properties.

Written descriptions of the construction program shall indicate the manner in which noise, soil erosion, glare, air pollution, fire hazards, safety hazards and the routes to be traveled by heavy construction equipment to and from, as well as within, the site in order to minimize damage to roads.

Where utility services are to be extended to the site, the final plat shall be accompanied by letters signed by a responsible officer of the utility which provides gas, telephone and electricity that has jurisdiction in the area, approving the utility installation and stating who will construct the facility.

The final plat shall be accompanied by a statement by the Township Engineer that all utilities and other improvements (both in the development and off-tract) are in their exact location and elevation, and that the drainage, erosion, stormwater control and excavation plans have been inspected and the interests of the Township and of nearby properties are fully protected. Those portions of improvements already installed shall be identified and the Engineer shall state that the developer has either:

Installed all improvements in accordance with the requirements of this chapter and the preliminary plat approval, with a maintenance guaranty accompanying the final plat; or

Editor's Note: See N.J.S.A. 4:24-39 et seq.

Action by the approving authority.

The administrative officer shall be authorized to reject an application as incomplete. The approving authority shall determine whether the submission is a complete application upon recommendation from the administrative officer and in consideration of reports from professionals retained by the approving authority. The approving authority shall grant final approval to a complete application meeting the standards of the Map Filing Law, N.J.S.A. 46:23-9.9 et seq., the standards of this chapter and, in the case of major developments, the terms of preliminary plat approval. In the case of a major development, minimal deviations from the conditions of preliminary plat approval necessitated by a change of conditions beyond the control of the developer may be permitted without submission of another application for preliminary approval.

If the application is found to be incomplete, the administrative officer shall notify the applicant, in writing, of the deficiencies within 45 days of submission. If accepted as complete, the administrative officer shall send the applicant a certificate of completeness indicating the effective date of the submission of a complete application. Final approval shall be granted or denied within 45 days of such effective date or within such further time as consented to by the applicant. An approved final plat shall be signed by the Chairman and Secretary of the approving authority (or the Vice Chairman or Assistant Secretary in their absence, respectively). Failure to act within the period prescribed shall constitute final approval and a certificate to that effect shall be issued on request of the applicant.

Whenever County Planning Board action is required by N.J.S.A. 40:27-6.3 or 40:27-6.6, the approving authority shall condition any approval upon timely receipt of a favorable report from the County Planning Board or upon their failure to act within the required time period.

Final approval of a minor subdivision shall expire 190 days from the date of municipal approval unless within such period a plat in conformity with such approval, including any conditions imposed by the approving authority and in conformity with the provisions of the Map Filing Law (N.J.S.A. 46:23-9.9 et seq.), or a deed clearly describing the approved minor subdivision is filed by the developer with the County Recording Officer, the Township Engineer and the Township Tax Assessor. Such plat or deed shall have been signed by the Chairman and Secretary of the approving authority (or the Vice Chairman or Assistant Secretary in their absence, respectively). The plat of a minor subdivision need not be in conformity with the Map Filing Law, provided that the developer chooses to file the minor subdivision by deed.

Final approval of a major subdivision shall expire 95 days from the date of signing of the plat unless within such period the plat shall have been duly filed by the developer with the County Recording Officer. The approving authority may for good cause shown extend the period for recording for an additional period not to exceed 190 days. No subdivision plat shall be accepted for filing by the County Recording Officer until it has been approved by the approving authority and signed by the Chairman and Secretary (or the Vice Chairman or Assistant Secretary in their absence, respectively) or a certificate has been issued as to the failure of the approving authority to act within the required time. The signatures of the Chairman and Secretary shall not be affixed until the developer has posted the required guaranties. If the County Recording Officer records any plat without such approval, the recording shall be deemed null and void, and upon request of the municipality, the plat shall be expunged from the official records. It shall be the duty of the County Recording Officer to notify the approving authority, in writing, within seven days of the filing of any plat, identifying it by its title, date of filing and official number.

The same zoning requirements, general terms, conditions and other rights applicable to a preliminary approval shall not be changed for a period of two years after the date of final approval, provided that, in the case of a subdivision, the plat has been filed with the County Recording Officer. The approving authority may extend such period of protection for extensions of one year, but not to exceed three extensions. Upon granting of final approval, the rights conferred by the granting of preliminary approval shall be terminated.

The developer shall supply sufficient copies of the approved final plat so the administrative officer can distribute one copy to each of the following: applicant, Township Clerk, Tax Assessor and any other agency or person directed by the approving authority; and, in the case of a major development, shall supply one translucent, cloth or Mylar copy to the Township Engineer.

§ 271-32.1 Performance and other guaranties.

[Added 5-15-2018 by Ord. No. 2907-18]

Establishment of performance guaranty requirement.

There be and is hereby established, within the Township of Maplewood ("Township"), a requirement that before the filing of a final subdivision plat or recording of a minor subdivision deed or condition of final site plan approval or as a condition to the issuance of a zoning permit, pursuant to the provisions of N.J.S.A. 40:55D-65, a developer, as defined in N.J.S.A. 40:55D-4, shall furnish a performance guaranty in favor of the Township in an amount not to exceed 120% of the cost of installation of only those improvements required by an approval, developer's agreement, ordinance, or regulation to be dedicated to a public entity, and that have not yet been installed, which cost shall be determined by the Municipal Engineer, according to the method of calculation set forth in N.J.S.A. 40:55D-53.4, for the following improvements, as shown on the approved plans or plat: streets, pavement, gutters, curbs, sidewalks, streetlighting, street trees, surveyors monuments, as shown on the final map and required by the Map Filing Law, water mains, sanitary sewers, community septic systems, drainage structures, public improvements of open space, and any grading necessitated by the preceding improvements.

The Municipal Engineer shall prepare an itemized cost estimate of the improvements to be covered by the performance guaranty, which itemized cost shall be appended to each performance guaranty posted by the obligor.

Additionally, the Township may also require a performance guaranty to include, within an approved phase or section of a development, privately owned perimeter buffer landscaping, as required by local ordinance or imposed as a condition of approval. At the developer's option, a separate performance guaranty may be posted for the privately owned, perimeter buffer landscaping.

Safety and stabilization guaranty.

A developer shall furnish to the Township a "safety and stabilization guaranty" in favor of the Township. At the developer's option, a safety and stabilization guaranty may be furnished either as a separate guaranty or as a line item of the performance guaranty. A safety and stabilization guaranty shall be available to the Township solely for the purpose of returning property that has been disturbed to a safe and stable condition or otherwise implementing measures to protect the public from access to an unsafe or unstable condition only in circumstances that:

Site disturbance has commenced, and thereafter, all work on the development has ceased for a period of at least 60 consecutive days following such commencement for reasons other than force majeure; and

Work has not recommenced within 30 days following the provision of written notice by the Township to the developer of the Township's intent to claim payment under the guaranty. The amount of a safety and stabilization guaranty for a development with bonded improvements in an amount not exceeding $100,000 shall be $5,000.

The amount of a safety and stabilization guaranty for a development with bonded improvements exceeding $100,000 shall be calculated as a percentage of the bonded improvement costs of the development or phase of development as follows: $5,000 for the first $100,000 of bonded improvement costs, plus 2 1/2% of bonded improvement costs in excess of $100,000 up to $1,000,000, plus 1% of bonded improvement costs in excess of $1,000,000.

The Township shall release the separate safety and stabilization guaranty to a developer upon developer's furnishing of a performance guaranty which includes the line item for "safety and stabilization" in the amount required under this subsection.

The Township shall release the safety and stabilization guaranty upon the Township Engineer's determination that the development of the project site has reached the point that the improvements installed are adequate to avoid any potential threat to public safety.

Maintenance guaranty.

The developer shall post with the Township prior to the release of a performance guaranty required a maintenance guaranty in an amount not to exceed 15% of the cost of the installation of the improvements which are being released. The developer shall post with the Township, upon the inspection and issuance of final approval of the following private site improvements by the Township Engineer, a maintenance guaranty in an amount not to exceed 15% of the cost of the installation of the following private site improvements: stormwater management basins, inflow and water quality structures within the basins, and the out-flow pipes and structure of the stormwater management system, if any, in accordance to the method of calculation set forth in N.J.S.A. 40:55D-53.4.
